Pat's Self-Saucing Chocolate Pudding Cake

A magical dessert that creates its own rich chocolate sauce while baking. This old-fashioned pudding cake combines a tender chocolate cake layer with a decadent sauce that forms underneath during cooking. The secret lies in sprinkling sugar and cocoa over the batter before pouring boiling water on top - creating two distinct layers that reverse as they bake. Perfect for casual family dinners or potluck gatherings, this comforting dessert delivers maximum impact with minimal effort and pantry staples.

FAQ
Can I make this without cocoa powder?
No, cocoa powder is essential for both the cake layer and the sauce formation. Without it, you won't get the proper chocolate flavor or texture.
What if I don't have brown sugar?
You can substitute with an equal amount of white sugar, though you'll lose some of the deeper molasses flavor that brown sugar provides.
How long does this keep?
Store covered in the refrigerator for up to 3 days. The sauce will thicken when cold but can be gently reheated to restore consistency.
